Optical Surface Accuracy

Optical surface accuracy refers to the difference between the actual shape and the desired shape of an optical surface. It is a crucial aspect of optical components and is typically measured in terms of fringes or waves that correspond to the laser wavelength used in the interferometer. And it is important to specify the expected […]

What Is the Difference Between a Mirror and a Lens?

Key Takeaways: The main difference between a mirror and a lens lies in their functionality; while a mirror possesses a reflective surface, a lens refracts light, with various types of mirrors including plane and spherical mirrors. Mirrors are typically made with a reflective coating, while lenses are transparent and refract light passing through them. Mirrors […]

Optical Tolerances: Impact and Costs

Optical Tolerances In real manufacturing, a certain amount of error will unpreventably occur between the measured value and the designed value. In terms of measurement, the difference between the maximum and minimum dimensions of permissible errors is called tolerance. If it is written on the drawing that “3.5 +0.05/-0.00“, “3.5” represents the reference dimension, “+0.05” […]

Image Recovery or Image Reconstruction of an Imaging System

Blurring is a significant source of image degradation in an imperfect imaging system. The optical system’s point spread function (PSF) describes the measure of blur in a given imaging system and is often used in image reconstruction or image recovery algorithms. Below in example of using inverse PSF to eliminate the barcode image degradation. Barcodes are […]

How to Read an Optical Drawing

An optical drawing is a detailed plan that allows us to manufacture optical components according to a design and given specifications. When optical designers and engineers come up with a design, they condense it in an optical drawing that can be understood by manufacturers anywhere.  ISO 10110 is the most popular standard for optical drawing. […]
